Line for guiding a medium

Abstract

An arrangement for guiding a medium, preferably compressed, gaseous hydrogen, is described. The arrangement encompasses a medium line, a cooling medium return line which surrounds the medium line, and a cooling medium feed line. The cooling medium return line and the cooling medium feed line are hereby preferably arranged in direct heat contact. The arrangement can furthermore be surrounded by a jacket tube.

1. An arrangement for guiding a medium comprising compressed gaseous hydrogen comprising a medium line, a cooling medium return line, which surrounds the medium line, and a jacket tube which surrounds the medium line and the cooling medium return line, and a cooling medium feed line, wherein said cooling medium return line and said cooling medium feed line are arranged in direct heat contact. 
     
     
       2. The arrangement according to  claim 1 , wherein the jacket tube is flexible. 
     
     
       3. The arrangement according to  claim 1 , wherein the space between jacket tube and cooling medium return line is at least partly filled with an insulating material. 
     
     
       4. The arrangement according to  claim 3 , wherein the space between jacket tube and cooling medium return line is completely filled with an insulating material. 
     
     
       5. The arrangement according to  claim 3 , wherein the insulating material is selected from the group consisting of polyurethane foam and vacuum insulation. 
     
     
       6. The arrangement according to  claim 1 , wherein provision is made within the jacket tube for means for fixing or stabilizing a line selected from the group consisting of the medium line, the cooling medium return line and the cooling medium feed line.
